An air conditioning device (1) is configured so that, in cooling operation, a refrigerant flows sequentially through a compressor (21), an outdoor heat exchanger (23), an expansion mechanism (24), and an indoor heat exchanger (41) and so that, in heating operation, the refrigerant flows sequentially through the compressor (21), the indoor heat exchanger (41), the expansion mechanism (24), and the outdoor heat exchanger (23). The air conditioning device (1) uses R32 as the refrigerant. The volume of the outdoor heat exchanger (23) is less than or equal to the volume of the indoor heat exchanger (41). A refrigerant storage tank (25) for storing the refrigerant is provided between the outdoor heat exchanger (23) and the expansion mechanism (24). |
